METAL BACK BUILDING ITATEBIAL.

Application filed February 28,1926. Serial No. 89,894.

This invention relates to building material, and has special reference to that class of material made from concrete, plaster or other compositions and used in the wall and roof structures of buildings.

The primary object-of my invention is to J provide composite building. material with a metallic backing, which facilitates installing the material, permits the material to be firmly anchoredrelative to an inner wall or support, protects part of the building material-while being handled, and insures a positive and reliable weather proof connection between superposed building material.

Another object of my invention is to provide, as an article of manufacture, a channel shaped backing plate in which may be molded and firmly anchored a composite slab, block, tile, shingle or facing piece of composite material susceptible to any desired exterior ornamentation. The anchoring of the material in the backing plate affords a tongue and groove connection with adjacent material and it is by virtue of such connection that the material cannot become laterally displaced after being installed.

A still further object of this invention is to provide a structure composed of an inner wall made of wood, an intermediate wall made of metal, and an outer wall made of composite material, said walls being secured together so as to provide a strong, durable and weather proof structure.

The above are a few of the objects ob-- tainedby the construction to be hereinafter described and then claimed, and reference will now be had to the drawings, wherein Figure 1 is'a side elevation of a P0111011 .of a building wall in accordance with my invention;

Fig. 2 is a vertical sectional view of the same;

Fig. 3 is a erspective view of a slab or block in accor ance with this invention;

' Fig. 4 is a perspective view of a channel shaped metallic backing plate adapted to form part of a slab or block;

Fig. 5 is a horizontal sectional view of a portion of the wall shown in F igs.- 1 and 2, and

Fig. 6 is a perspective view of a portion of a slab or block showing another form of anchoring member for the slab or block.

The reference numeral 1 denotes a pressed sheet metal backing plate substantiall rectangular in elevation and provided wit 1onanchoring rib 4 with the outturned portion of said flange of greater depth than the rib also as to form a longitudinal tongue 3.

The lower flange 3 is inturned and then' outturned to form a channel groove or seat 6 and this seat' serves the oflice' of an anchoring rib, similar to the rib 4, as will appear hereinafter.

The plate 1 has a protruding end7 apertured or provided with a nail opening 8 for plate securing purposes, and the opposite end of the plate is offset to provide an overlapping flange 9.

Mounted against the back plate 1 in the channel formed by the upper and lower flanges 3 is a composite slab or block 10 that may be molded on the plate 1 and rovided with a suitable outer ornamental ace. In molding the slab or block the rib 4' and the seat 6become imbedded and anchored in the upper and lower edges of the slab or block block relative to the plate and it will be noted that the-flanges 2 and 3 cooperate with the plate 1 in protecting the back part of the block. The end 7 protrudes from the block 10, but the block overlaps the flange 9.

As illustrating a sample of an installation of the building material, I show studs 11 and siding 12 as formin an inner wall. A layer or row of the b ocks 10 is placed against the inner wall and secured thereto by nails 13. The blocks are placed end to end and consequently the flanges 9 overlap the protruding ends 7 of adjacent back lplates, see Fig. 5. Another row or layer of locks is placed in position on the lower layer or row with the seats 6 receiving the tongues 5, as best shown in Fig. 2, and in this manner an outer composlte wall is formed having a metallic backing, constituting an intermediate metallic wall which fully rotects the inner wall formed by the sidlng 12.

When the blocks are of sufiicient length the ends thereof may be secured direct to the studding, without using siding, in which instance the back plates afford a metallic side.

provide a malleable apertured lug 16 that may be secured to a stud, siding or suitable support. This outstruck lug may be left in the plane of the flange 15 until the block is to be installed and then it may be bent 'With one or more of the lugs at each end of the back plate or at points intermediate the ends thereof, the block may be firmly secured relative to a sup ort.

Obviously during the aying of the building material any sealin material, as paint, tar or the like can be p accd on the ton ues 5 so that the samewill become scale in the seats6 and such sealing material may be used at the ends of the blocks, should occasion requirei Again, the backing plates may be apertured or cut away to reduce the weight .of said plates and save material;

Such other changes as are permissible by the a pended claims may be resorted to without eparting from the scope of this invention.

What I claim is 1. The combination of a composite piece of material having upper and lower edges, a metallic tongue in the upper edge of said piece of material, a metallic seat'in the lower edge of said piece of material, and means connecting said seat and tongue independent 40 of said composite piece of material.

2. The combination called for in claim 1, wherein said means isin the form of a plate as a backing for the composite piece of material.

3. The combination of a composite piece of material having upper and lower edges, a metallic tongue in the upper 'edge of said piece of material, a metallic seat in the lower edge of said piece of materiahand a backing 50 a plate for said composite iece of material said backing plate protru ing from one en of said piece of material for securing purposes. i p

In testimony whereof Iaflix my signature.
